Socket bit (6-point) 1/2" 11 mm EPM E-400-1011

EPM 6-point socket bit 1/2" 11 mm E-400-1011 is a precision tool designed for fastening and loosening hex fasteners with an 11 mm head size. The socket features a 6-point profile and a 1/2" drive interface, intended for use with ratchets, torque wrenches and extensions. It provides focused contact on fastener flats to minimise slippage and reduce the risk of rounding, making it suitable for automotive, industrial and general maintenance applications where reliable torque transfer and tool durability are required.

Advantages

The 6-point geometry ensures secure engagement with hex fasteners, concentrating force on the flats rather than the corners to lower the chance of damage. The 1/2" drive interface offers compatibility with a wide range of hand and power tool accessories, allowing straightforward integration into existing tool sets. The socket is sized for common 11 mm fasteners encountered in engine work, machinery maintenance and assembly tasks, offering consistent fit and predictable torque transfer.

Suitable for

• Automotive repairs and maintenance (engine components, brackets, fasteners)
• Industrial assembly and equipment servicing
• General mechanical and workshop tasks requiring an 11 mm socket

Key specifications

• Drive type: 1/2" square drive
• Socket profile: 6-point (hex)
• Size: 11 mm across flats
• Intended use: hand-operated ratchets, torque wrenches and extensions
• Application areas: automotive, industrial maintenance, mechanical assembly

How to use

Select the 11 mm 6-point socket and attach it securely to a compatible 1/2" drive ratchet, torque wrench or extension. Position the socket squarely over the hex fastener, ensuring full engagement on the flats before applying torque. When tightening, apply steady force and observe the required torque value if using a torque wrench. When loosening, use controlled force and appropriate leverage; if a fastener is seized, consider applying penetrating lubricant and use incremental force to avoid damaging the fastener or tool.

Usage recommendations

Use the socket with tools rated for the required torque and avoid impact tools unless the socket is specifically specified for impact use. Inspect the socket for wear or rounding before use and replace if deformation is visible. Store the socket in a clean, dry tool case to maintain fit and prevent corrosion.
